This AMD65 kit has the original length barrel which we machined in house. For this to be built as a rifle you need to use a barrel extension or it can be built as-is for an SBR. Make sure to follow all NFA rules when using this kit with the shorter barrel. Non chrome barrel with wooden grips

The barrel is 12.5" long and is made in the USA and marked U.S.A. 7.62.

Keep in mind these kits are sold as is as far as furniture and finish are concerned.

Ok, now that that is done here is what we've done...

All journals are measured as well as the parts to be pressed to make sure the fit is correct. We set the headspace and check it twice with a GO gauge, with a live round (not fired just for testing the bolt closing) then with a NO-GO gauge. After setting the headspace we drill the barrel pin hole and ream for the new barrel pin. The pin is pressed most of the way through so you can press it back out the same way it was put in to remove the barrel for installing rivets. If you don't want to use rivets then just press the barrel pin the rest of the way in.

The rear sight, gas block and front sight are pressed on after the barrel pin is installed to make sure everything fits correctly on the barrel. We use a special fixture to press on each piece to ensure proper alignment.

When reinstalling the barrel I recommend use a headspace gauge again to make sure you install it back to the original setting.
